Updating SAP ABAP Systems on UNIX and Linux: SAP MaxDB

Resetting the Update

The Software Update Manager offers the option to reset the update.

Prerequisites

  • Make sure that the downtime has not yet started.

    As of the beginning of the downtime, a reset is not possible anymore. To reset the update after the downtime has started, use the system backup created before the SUM process.

  • Make sure that the SUM directory has not been cleaned up.

    After the update procedure comes to an end, the Software Update Manager offers the option Cleanup in the More menu. It cleans up the SUM directory and terminates all running SAPup processes on the server. Note that after a cleanup, you cannot reset the update. For example, you cannot carry out a manual reset on operating system level after a cleanup. Use a system backup created before the update procedure. Note that a cleanup is obligatory after a reset has been finished.

  • If you use the database migration option, make sure that anyDB is still available.

Context

When you choose the Reset option, the system is set to a state that allows the update procedure to be restarted from the beginning.

Excluding Customer-Specific Languages

The removal or modification of customer-specific languages in the tables T002C and TLSY7 is executed immediately. A later reset of the update procedure does not restore the entries. See also: Excluding Customer-Specific Languages.

Procedure

From the SUM UI: Menu Bar, open the More menu and choose Reset.

This possibility depends on the phase that the update procedure is currently going through. The update procedure consists of phases that can be reset and of phases that you cannot reset directly. Whenever you are inside a resettable phase, the Software Update Manager offers you the Reset option. If not, choose on the SUM UI Back repeatedly until you are in a resettable phase and the Reset option appears in the More menu. If the update procedure has not progressed far and you choose Back repeatedly, the Welcome dialog appears.

After you have chosen Reset, the Software Update Manager indicates afterwards the successful reset procedure and asks you to clean up the SUM directory. Choose Cleanup in the More menu. After the cleanup is completed, a message appears on the user interface that the SUM ABAP server processes ("SAPup") have been ended. You can close the browser window or the browser tab page, or you can start the update procedure from the beginning.
